Research And Analysis Of Ship’s High Voltage Shore Power

Ship shore power technology refers to after the call to the port for the wharf,shore power,via cable connection by the shore power to provide power for ship power equipment technology,After the ship on shore power,shut down power diesel engine,this vessel from shipping port to port,the electricity required to ship all electrical equipment are provided through the shore power source.Through access to shore power supply this kind of form,the power system of power grid system to reduce costs,increase the energy utilization ratio,reduces the noise caused by diesel generator power substation and waste pollution problem,Improve the quality of the air port,also the response of the country’s energy conservation and emissions reduction and sustainable development strategy.Around the national standards of power grid voltage and frequency of ship power grid with quite a number of countries of different facts,based on the analysis of the structure and principle of shore power supply system,focusing on the power supply system of frequency conversion link modeling,simulation analysis and research,the efficiency and superior electrical properties of stationary type shore power supply.Analysis process is composed of static type of shore power supply first,describes the shore power supply power supply and the configuration form,the topology of the shore power supply is analyzed,it can be divided into two parts of the three-phase PWM rectifier and inverter respectively,using the three-phase static coordinate system and two-phase synchronous rotating coordinate system,respectively,of the above two parts modeling,through the feedforward decoupling control strategy in the circuit software for the simulation research.At the end of the paper according to the China shipping group,shore power system as an example,the visual simulation system of shore power system,further improve the function of the turbine simulator stronger,of turbine management education and training in our country,the corresponding contribution.
